Non-ferrous Minerals Geological And Geographical Information Systems Design

GIS is a technique of newly arisen spatial information that rise in recent years, and is a thing of various subjects that cross. It can efficiently manage, analyze information having spatial structure and export result. Along with continuously develop of GIS, it is already extensive application on energy and transportation, city planning, resources evaluation, land exploitation etc. and exert the great function in the national economy.This research applies GIS to geoscience's fields. By material item, this paper expatiates on integration about GIS and geological database from development and application. On the development means, we develop this system by ComGIS, which is most one of the popular development modes at present. This system is different from a traditional Database Management System in query, management and analyses essentially. The mostly contents of this paper are as follows in brief:In the first chapter, it introduces research background, source for whole study works and its significance, and makes the essentials elucidation with main special features.This paper gives an overview to GIS in chapter 2, and it not only explains GIS's essential but also show how to apply from its origin, development and material application. GIS is still a thing that keep on the development, along with continuous progress of science and technology, the more new methods and new technologies will be digged in GIS and it necessarily will obtain the larger applied space.In chapter 3, it puts great emphasis on analyzing differentiation and contact during spatial database and geology database, compares their outside manifestation and actual contents , discusses both it, announce to essential of geology database. Otherwise, it describes spatial database's design of GIS.Spatial database's planning is important for GIS. If not data, GIS will be empty. It will exert adequately some advantages if it has an efficient spatial database design plan and optimizes data, planning and management when having data. Spatial database design includes the spatial image database's design and property's database design. In a general way, property's database is frequently neglected in spatial database and spatial image database's design is stressed excessively. This emphasizes demonstration but neglects practicability. In view of this research practicability, at design we emphasized that two kinds of designs go forward together.In chapter 4, it describes development environment, running environment and system's function. In developing environment, we adopt a GIS platform for MapX ofMapInfo Co. It is a second-developing component on OLE and MapX's function in management and analyses is not less than Maplnfo Professional's. In system's function design, we stress query and management of spatial data and property data by connecting actual matter and choose a rational way. In this base, we add some functions as analysis and exporting image etc.Chapter 5 discusses analysis and application to spatial data and property data of mineral space database and working level database for geological factor in macro approach and micro approach. This research's data is complex and comes down to all my country. We integrate some known mineral space and working degree data and stratum, constitution, magma rock and geochemistry information and analyze their controlling mineral models and reasons. Final we announce their potential rules by layer's image. Particularly, big scale spatial data that is contact with diggings is usually more available than the other form in announcing to inside rules.
